I. DOUBLE-ACTING HINGEVAND oHEcKfl Ap plic ation file d June 30,

This invention is a combined doubleacting hinge and check adapted for use in connection with swinging doors intended to Another object of the invention is to provide a device which canbe quickly and accuspecification, Fig.

rately. adjusted with, reference to the door or the door adjusted with reference thereto, and a still further object .is to provide for the simple and easy adjustment or regulation, of the device whereby the amount ofchecking can be increased or decreased, as desired. With thesevarious objects} in i.view, the invention consists in the novel features of construction and in the manner of combining or arranging the same, allof which will be fully described hereinafter and setforth in the appended claims. r 1 y In the drawings forming af part of this i 1 is a view of a door connected with a c'ombined' double-acting hinge and door check embodying m'y'invention and this view also includes the: novelconstruction of the upper pintle usable in connection with the door; Fig. Zis adet ail sectional view of such upper pintle and means" for adjusting the same; Fig.3 is. a horizontal sectional view of the combined hinge and check with theparts arranged .in the positions they, oc cupy when thedooris closed; Fig, 4 isa vertical sectional view of the same; Fig. 5 is a sectional elevation on the line 5 5 of Fig. 4:; Fig. 6 is a sectional view on the line 6-6 of Fig. 4c; and Fig. 7 is alhorizontal sectional view showing the position of the cam, piston and yoke when the door is' being swung uponitspivotb I r Y First of all it .will be understood that the combined hinge and check is concealed in thefloor, and when set 1n cement is'prefer ably contained w thin. an outer metal casing A sunk into an opening in the ceniehtfloor provided with lateral top "flanges suitably seated in a recess or mortise 'infthe, fioor,-tl1is outer casing bBlligPl'OYlClGd with acoverj A which is secured to the flange upon the top in which pivots the pintle or pivot D, this a in a mortise cut in the bottom of the door D,

the opposite e'nd of the bar having a head 1) into which fits the regulating screw D by means of which the bar D is positioned with tying the rollers G at the rear end which approximately 90. from its initial position.

of the casing and rests flush-with the floor, as most clearly-shown.

Within the casing A, at one end thereof, is arranged the hollow castingB open at the top and also atoneend and connected to this open endis the cylinder C, this cylinder being closed at the opposite end and provided with ports and a regulating. valve. hereinafter morefnllydescribed. The hollow. casting Bhasa suitable bearin-g B produced in the bottom thereof and pintle or pivot passing through the. screw cover B provided with the centralbearing portion B". This pivot or pintle D projects upwardly through the'screw cover B of the hollow casting and is provided at its upper end with the cross pin D which fits into the slotted head D of a bar Dtwhich is seated reference to the door, and consequently the correct relation established between the door and thepintle. v

'The pivot or pintle D has a cam E rigid therewith, said cam working betweenthe upper and lower at P to receive the pintle D, this yoke carcontact with the rear portions of the cam and this-yoke also carries a roller 11 with which the front portion of the cam contacts, said cam having-indentationsE into which the rollers F and G fit when the door is to be held open ineither direction at a position If desired only one indentation need be made so as to holdthe door open on one side only.

The forward portionfot the yoke F projectsinto the cylinder C and, is pivotally connected to the rear end of a piston I work ing inthe cylinder, the rear end of the cylinder being reduced to provide ashoulder 1 against which one end of a coil spring K contacts, theopposite end of this spring contacting with the hollow casting B, as most clearly shown in Figs, 3 and 7 v The connection between the forward end of the yoke and the piston isby means of a pin F passed vertically through the piston and yoke,'the yoke end being arranged within a curved recess cut in the end of the members of ayoke F slotted tending I understood that any suitable I ployed to prevent piston and so shaped as to permit a limited amount of lateral movement of the yoke with reference to the piston. The piston is bored centrally and loi'igitudinally to receive a tube L screwed into the end of the cylinder. I

The cylinder is formed with a. vertical chamber C having a reduced lower end C and a tapered seat C between the chamber C and reduced portion C and leading from this reduced portion O is a passage G coinmunicating with the cylinder forward of the piston. A passage 0" communicates with the tube L and thereby establishes com'n'iunication between the chamber C and the rear side of the piston.

Located in the chamber C is a'valve pin M having a tapered end M at its lower end adapted to cooperate with the seat C to regulate the passage of fluid therethrough, the upper end of the pin being threaded as shown at M and working through a collar or plug M screwed into the upper end of the chamber C there being interposed a packing M to prevent leakage. I

'There is an opening A in the cover plate A to permit the adjustment of the regulating pin or valve, said pin or valve being provided at its upper end with a slot for the reception of ascrew driver or other tool for the purpose of adjustment.

The piston also has a longitudinal passage N reduced at its rear end and providing a valve seat N against. which the ball valve N seats during the forward movement of the piston, this ball valve being held in place by means of a. pin N exacross the forward end of the passage N.

It will thus be seen that there is pro vided a double check, one carried by the piston and the other by the cylinder, the latter being adjustable to regulate the passage of fluid therethrough. In practice it is preferred to employ oil as the fluid controlling medium but it will, of course, be fluid can be employed, and in this connection air will be considered a fluid for such purposes in case it should be desired to dispense with a liquid controlling medium.

A leather washer X is placed between the screw cover B and the casting and I also employ a leather washer Y and disk Z surrounding the pintle where it passes out of the screw cover, these washers being emthe escape of oil or other checking liquid.

As'the door is swung ineither direction, the yoke will be forced rearwardly drawing with it the piston. During these movements fluid will ton head both through the check valve and the central tube L, but upon the return movement, the check valve will seat to prepass through the pisthe dooris moved in either direction.

In operation the outer casing is 'lirst positioned in the floor and the hollow casting with cylinder connected thereto is arranged within the outer casing and thecover plate A is then securely fastened in place flush with the floor. The door to which the bar D has been attached is then positioned upon the pintle D and cross pin D vand the door is properly centered by means of the adjusting screws D in order to maintain the lower end of the door in the proper relative position with reference to the com: bined hinge and check.

At the upper end of the door there is placed a pintle socket 0 into which fits the upper pintle P, this pintle being-arranged in the socket Q, arranged at the top of the door frame, this socket being slotted as shown at Q/ topermit the movement of vthe adjusting finger R fitting into the upper end passage of fluid at that point thereof the pintle P and provided with, a thread edopening at its other end in which works a screw S thehead of whichis countersunk in the plate portion of the upper socket. This screw is held against vertical movement by means of a washer S, said Washer holds the screw against vertical movement but permits rotation.

In operation the socketQ is inserted in the door frame and the pintle P is drawn upwardly by turningthe screw S, ,moving the finger R upwardly, withdrawing the pintle into the socket. Thesocket-portion 0 having been previously positioned in the top of the door D, P, and whilethe door is turned :to a position at right angles, the screw S is turned in the reverse direction, bringing the pintle P downwardly into the socket O. 7 It will thus be seen that weprovide .asimple construction of adjustable pintle for the upper end of the door as well .asa simple and eflicient hinge. and check for the lower end of t-he'door.

Having thus described .our invention, what we claim is,:.- I
